MPlayer interrupted by signal 8 in module: play_audio                           
- MPlayer crashed by bad usage of CPU/FPU/RAM.                                  
  Recompile MPlayer with --enable-debug and make a 'gdb' backtrace and          
  disassembly. Details in DOCS/HTML/en/bugreports_what.html#bugreports_crash.   
- MPlayer crashed. This shouldn't happen.                                       
  It can be a bug in the MPlayer code _or_ in your drivers _or_ in your         
  gcc version. If you think it's MPlayer's fault, please read                   
  DOCS/HTML/en/bugreports.html and follow the instructions there. We can't and  
  won't help unless you provide this information when reporting a possible bug. 

Help me! please!
Thank you!
